Addictive!

Yes, addictive, lots of good rewards for regular play, works well and dev responds to suggestions etc

Fun!

This… is a surprisingly fun game. Great progression, and at least in the beginning so far I don’t feel like anything is unfair or punishing. Really enjoying the game!!!

it could be worse

it is an incremental game
you are just waiting on timers
it counts on your impatience to make money
it is part of the modern F2P malaise
and broader cultural sickness

it gets 2 stars because there is some actual gameplay in here
just one piece though
the puzzle of arranging buildings
it's actually kind of interesting
but even that gets old
because you continually have to redo it
and it does not evolve
there are only 3 building types
it's always the same thing over and over

Big improvement

A lot better than one with more purpose

Gut aber Verbesserungswürdig

Ich habe das Spiel anfangs sehr genossen. Die ersten paar Spielstunden waren sehr spaßig und ich hab sehr viel Fortschritt gemacht. In den späteren Leveln (nach Gaskraftwerk) ging aber alles eher schleppend voran. Ja eine tycoon ist darauf aufgebaut erstmal Geld zu sammeln und upgrades zu machen, jedoch dauert es etwas zu lange. All in all good
